' Application led March 8,

Toy all whom t may concern:

^ I'This invention relates to section'carriers vtion of track, usually about siX feet long,

in front of the steam shovel so that the latter `can move forward. The vshort 'sec-y tion which is swung around the front of the shovel is the onewhieh the steam ,shl

e picking up vof this section and carrying same forwardVV and placing in the proper; position,V involves arduous labor. To pull Vthe spikes, remove the rails7 and carry the Atiesforward singly, la'y Vthem down and re-l construct the section,v involves much labor.v In -my improved device the section in the rearof'the steam shovel is picked up bodily and intact and placed in position for-advancing the steam shovel in a manner greatly reducing the labor and ltime involved in the operation; v A

One 'object of the invention is to trans- .ferfa section vof'track bodily from one po-' sitionto another with respect toa steaml shovel in a simple, novel and efficient manner whereby arduous labor is eliminated and time-and money-are saved.

Anotherobj ect is to provide a simple andsafe trolley arrangement which vis adaptedl` 40 to revent the trolley from being derailed.

nother object is to-provide a collapsible trolley' track arrangement whereby the A ysteam shovel equipment mayjoccupy the lminimumamount of space, useful particularly in moving the steam shovel from one location to another. Y

' The seyandV other. 'objects are accomplished by'means of the arrangementxdisclosed on fthe accompanying Sheets of drawings in" which-- Figure-1 isA a side elevation of asteam Shovel equipped with my vsection carrier;.

Referring tothe iguresof the drawings,f it 4will be noted that I havefillus'trated my invention in connection with a steam shovel v equipment which maybe designated gen? a, plan View of the arrange'- erally by the Vreference character 10. The

steam shovel equipment. among other things;

.includesa car frame 1l mounted on trucks l2 and having the usual housing'l yin whirh; is' mounted the engine and other.'necessary machinery Yfor actuating vthe clipper, .not Y' shown, carried atthe end of the dipper'supv' port '14.

means for transferring a section of tracli,l including two rails and the ties whichl con-v neet` same from one end ofthe shov'el'totheV4 other in order that the shovel may approach more closely a' bank of material to lbe dug,"V

especially after the dippery has beeneX- tended the maximumamount for removing the material in the bank. To` accomlThis invention has to do primarily with l 5 plishv the desired results,-'.I have mounted-l lengthwise ofthe shovel ateither side thereofftrolleytracks l5, the tracks in. this' case extendingfr'om end-to end of the shoveL and being'connected atl their rear ends byj a transversely varranged ytrack '16. The f mally lregisters with a trackfsection 17,A

which in turn is suitably supportedro the shovelm 1 7.

yWhen it is desiredvtotransfer 1a tr'ac'lffsegf 1' tion from one end of the shovel tothe other., Y

forexample. from therear endto-the front..

' actuated to wind the cable thereon,jthe

end, for the reasons stated, al rigging 19 is secured to the track section in any suitable manner, the rigging beingr connected ,to a

Ychain 20, which is operatively connected to a block 21 carried by a trolley the wheels 23 of which travel4 upon the lowerv trolley track Vsection orarm 17 and which in this case might be aliuid propelled motor.`

This motor lincludes a drum having connected thereto a cable 26, which is connected` tothe trolley 22, so that when the drum is trolley 22, and therefore the track section when secured tothe trolley, istransferred `forwardly from thc rear end ofthe shovel.

To prevent the trolley 22 Vfrom 'dropping to the groundfro'm the track 15, it is necessary thatthe track/section or swingably mounted arm`r17 Vbe inflregister with the.. track15`vatv the time `that the trolley 22.

moves forwardly from the latter. To Vmake the connection between track15 'and Vthe associated arm 17 secure and safe, I have pro' vided` connecting means therebetween,

shown particularly in Figs.Y 4 landt.- This p 'connecting means includesVV 'a yslidably `mounted memberr 27 mounted over the top liange ofthe railv 15, the forward end of which passes between upstanding proj ections v28 .carried onthe upper flangeof the rail section 17.-Therefore, when it Vis desired to` transfer'the trolley from'track 15 to tra-ck section 17 ,the slidably. mounted member.A

27 is.in locking relationship with respect to yits associated locking members 28. Secured to the track 15 is a support 15 which `extends under the free end of arm 17 for sup-. porting the latter when it isfin alinement M with tra'ckr1'5.V 'In order that' the trolley lin lto'fa bell crank lever 31,- whichin turn isi V.pivotally' connected at 32 to a bracket`33. After the trolley has been transferred 'safely from track 1'5vto track section 17,l as shown: VinY Figs.j4 and 5 ofthe drawings, thelock Ving boltj29maybefdropped to form a safety* device to prevent the' vtrolley 22 from acci-f.

may be transferred' from track 15 to track section ,17, it 1s lirst i'necessaryto move a lockingbolt 29 out ofthe path of movement ofvthet'rolley wheels. This is done by drawof downwardly upon `a cable 30 connected dentally" rolling offthetrack section 17,

Y V especially' :during a yswinging movementofv 'Y the latter; Preferably Vthe lock bolt 29 isV of such weight that it automatically moves. into its locking position when the cable 30v lis released. In order that the track section `17 may be swung away from the track 15,

it is necessary to withdraw the sliding member 27 from its associated locking projections 28. This is done by drawing down wardly uponV a cable 34 secured to a bell crank lever 35 pivoted at 36 to a bracket 37, 'one arm of the bell lcrank beingslotted to rslidably accommodate a pin or projection 38 carried by the sliding member 27. Preferably the sliding member 27 is normally` held in its locking positionpandwhenwithdrawn automatically returned to such position by any suitable means, such as a spring 38221 do not limit myself to this1mechani cal arrangement to accomplish this" end,` as. obviously other detailS'O.Construction could be designed. When the trolley is safelyl on the swingably mounted track section or arm 17, as shown in Figs. 4 andY 5 of the drawings, the track section may be swung about cated by dotted lines in Fig. 2,V until the track section is placed in a position toaline with Vthe ltrack sections upon which the shovel ismounted. Itis necessary-that the vthe member 18 as a vertical axis, as `indif arms 17 'be of `sufficient length to swing the. 'y

tracksection VVclearY ofthe kjacks 39., whiclu,

as is understood,are necessary to support theshovel through arms 40 to prevent the shovel from tipping over. By referringA to, n

Figsj2 Vand 3, and particularly thevlatter,A`

it .will be appreciated that itis necessary to l swing thetrack section 24 outwardlyv a conl- Vsid'erable distance toVV clear fthe jack mechaf'A Y Ynism 39. By the arrangement here, shown such is done in a simpleJ and satisfactoryY manner. lVhen the shovel is lstationed at a given location,the tracks 15 are retained in their oifset position with respect 'to the housingv '13, as shown in thefgures ofthe drawing.

However, whenr it is desiredl to move the -shovel from one location'to another, which may be a considerable distance aWay,-it is.; Y

desirable Vfor clearance purposesV to 1 have the this objectvl have 'provided a collapsible mounting--forrthe rails 15,Y including sup.-

lporting bars41, which normally space the tracks V15 from'the'side of thev housing 13.

These supporting members 41Ia'repivotally mounted at their innerends` at .42.1- Diiag-V l Y onally extending tie bars 43 assist to sup.

port the tracks115. These tie rods y43 are rails 15 occupy less space. YTo accomplish.'

pivotally connected at their upperv ends.- l Y ByV means ofy Vthis arrangementthe tracks 15 may bemoved` toward thecar sides; as*

the members 41..'sw'ing inwardly with; rei.,

dotted lines in Fig.V 2 of the drawings.

Normally it will be understood,VV however-,1;

that the ltracks -15 are locked in their extended position by removable tie rods 44.

By means of this equipment, track sections may be moved from one end of the shovel to the other in a simple, safe and economical manner and the extending parts of the equipment be moved into positions requiring a relatively small amount of space when it is desired so to do.

It is my intention to cover all modifications of the invention falling within the spirit and scope of the following claims.

I claim:

l In steam shovel equipment, the combination of a trolley track extendingy from the front to the rear of a steam shovel for `carrying a track section over which the shovel moves, and a jib crane on the front end of the shovel having an arm which in one position registers with the trolley track and is sufficiently long to permit the carried track section to clear jack mechanism supporting the shovel and whereby said track section may be placed in proper position.y

2. In steam shovel equipment, the 4combination of a trolley track extending along the side of the shovel for transferring a track section over which the shovel moves, and a (jib crane on one end of the shovel having an arm which in one position registers with the trolley track and is sufficiently long to move the track section clear of jack mechanism which supports the shovel and by means of which the track section may be transferred to the proper position.
